I replied to the other thread.
I think this is what you want to try next. 18" with 5/8 center hole super high lift notched fusion blade. Maybe this blade will be the holy grail for your mower. If not you may just have to use the oem blades.
Here is the fusion chart. They have multiple fusion blades that will fit your mower.
